If I were in the shoes of chinese leaders I would counter immediately by telling telling the US public that the real danger to National security is not China or its companies but the fact that the concerned politicians who wrote the report are highly incompetent people. A day before the elections I would issue a statement that China would stop buying debt and would diversify its interest. Now that would teach the politicians a real lesson as the dollar would plunge to an all time low and the creditworthiness of the US would go down the drain. It is almost pathetic that politicians try to make a scapegoat out of a company. Microsoft and Oracle are bigger threats to China than Huawei to the US.
